Introduction: Anticholinergic medications which are commonly prescribed to older adults can produce more pronounced adverse effects compared to the younger population.
Objectives: To investigate the prevalence of polypharmacy, describe the prescription patterns of anticholinergic medications, determine the prevalence of exposure to high-risk anticholinergic cognitive burden (ACB) medications, and identify the potential predictors of exposure to high-risk ACB medications in older adults in a Nigerian secondary hospital.
Methods: This cross-sectional study that included older adults prescribed at least one anticholinergic medication was conducted at a secondary care hospital in Nigeria. The study data were initially summarized using descriptive statistics, whereas multivariable logistic regression analysis was used to identify the potential predictors of exposure to high-risk ACB medications. In this study, the cumulative ACB scores were dichotomized into low risk (score 1-2) and high risk (score ⩾ 3). A value less than 0.05 was considered to be statistically significant.
Results: A total of 256 older adults were included in this study; 113 (44.1%) had polypharmacy, whereas 26.6% (188/256) were exposed to high-risk ACB medications. Of a total of 391 anticholinergic medications used by the population, furosemide (36.57%) was the most commonly prescribed. The adjusted multivariable logistic regression analysis indicated that patients who had acute diseases were 2.5 times (adjusted odds ratio (AOR) = 2.49, 95% confidence interval (CI): 1.40-4.45) more likely to be exposed to high-risk ACB medications than those with chronic diseases.
Conclusion: The study demonstrates a high prevalence of polypharmacy and exposure to high-risk ACB medications suggesting the need for pharmaceutical care in this high-risk population. Older adults' exposure to high-risk ACB medications was significantly associated with prescriptions for acute diseases.

African, Caribbean, and Black (ACB) women are overrepresented among new HIV diagnoses due to social and structural factors. This study seeks to create, implement, and evaluate a community-based peer-led intervention to improve access to HIV prevention and care for ACB women in Canada. This multisite, five-year project, using community-based participatory research, implementation science and evaluation frameworks, will be implemented in five non-iterative phases.

The deep-sea ecosystem, a less-contaminated reservoir of antibiotic resistance genes (ARGs), has evolved antibiotic resistance for microbes to survive and utilize scarce resources. Research on the diversity and distribution of these genes in deep-sea environments is limited. Our metagenomics study employed short-read-based (SRB) and assembled-contig-based (ACB) methods to identify ARGs in deep-sea waters and sediments and assess their potential pathogenicity.

The sphenoidal sinus septum is one of the most important landmarks during endonasal endoscopic transsphe-noidal operations. During routine coronal sectioning of the face, we found a variant Y-shaped septum in the sphenoidal sinus of a female cadaver. This unusual septum was found between two sections (anterior and posterior sections) and located inferior to the pituitary gland.

We aimed to compare the analgesic effects of intermittent multiple infiltrations between the popliteal artery and capsule of the posterior knee (IPACK) combined with adductor canal block (ACB) and intermittent ACB alone in patients with flexion contracture knee arthritis undergoing total knee arthroplasty (TKA). Forty-six patients who underwent elective unilateral TKA were divided into two groups ( = 23 each): intermittent multiple IPACK combined with ACB (group IA) and intermittent multiple ACB (group A). ACB was performed with 20 mL of 0.
